stopper mechanism for bowls, lavatories and other analogous receptacles. I One of the salient features of the present eon'iparatively inexpensive stopper operas ing mechanism having those parts requiring adnistrnent arranged exteriorly of the cas ing, so th at the necessary adjustments can 19 with greater facility than Where the adpisting parts are positioned interiorly otthe casing;

Hewett-fore in waste stopper, in order .to 15 a proper operating of the considerable length and fittings at this type,- the effectively insure arts, has beeiiof ended a consider} able distance into the casing, thus requiring proportionate In the present lengthening" or, the casing. development, the operating mechanism has been so simplified as to very inateri ally shorten the length of the waste stopper and easing, thus not only effecting a consi derab saving in the amount of metal required, but also. greatly enhancing the ap of the installation giving the and lts associated parts a more com- 5: pact arrangement than has previously been illustrated and improved possible in similar fittings.

in the accompanyingdrawings we have one embodiment of our invention,

Referring to the drawings wherein like numerals indicate like parts in the various outlet in t he bottom of the bowl- "observed that the 1923. Serial. No. 637,525.

A sleeve fitting l2 having' externally screw threaded portion passes through the waste outlet and extends belowthe bottom of the bowl 10, to which it is secured by the gasket 13 and the nut 14. The upper end lit the sleeve 12 is provided with; a periph eral flange 15 adapted to engage a packing 1G,- puttyor cement, preferablybeing seated in an enlarged recess in the bottom of the bowl to finish any neven urface and revent the accumulation of filth. ItWil be packing 13and 16 tendsto f desired the packing lfl nay be To the lower end of the" sleeve 12 is secured, preferably by enga ing the threaded portion of the sleeve, the adp'istable casing 1'? which is provided with the offset chamber 18 extending outwardly therefrom. To the open lower end of. the casing 17 is threaded or otherwise suitably secured a plug 20, to which is suitably connected the end 01 the trap 21.

A hollow tubular stopper 22 is telescopically mounted in the sleeve 12 and projects a short distance within the casing 17. The upper end of said stopper 22 being, formed with a conical head 23 adapted to be seated against a correspondingly conicalseat formed inthe end of the sleeve 12, so as to provide a Water tight joint when the stopper is in closed position. In order to permit passage of water from the bowl to the waste outlet, the stopper 22 is provided with a plurality of wall slots 24 adjacent the conical head 23. The stopper 22 is maintained in position and prevented from being removed from the sleeve 12 by means of a' longitudinal slot 25 which is engaged by a screw 26 threadedly secured to the casing 17. The lower end of the stopper 22 has formed about the outside thereof diametrically opposed interrupted grooves 27 having flat sides 28, as shown in Figs. 2 and 5, so as to pe m t the rea y rem val of the st pp r from the casing when it is rotated to bring the flat sides in line with the actuating fork, presently to be described.

The offset chamber 18 receives the inner end of a lifting fork 29, the arms 30 of said fork being provided with the inwardly eX- tending pins orrollers 31 adapted to loosely engage the interrupted grooves 27 in the stopper 22.

' With this construction, it will be seen that when it is desired to remove the stopper 22 from the bowl, the same is easily accomplished by withdrawing the screw 26 from the slot 25 and turning the stopper so as to have the flat sides 28 thereof in alignment with the pins 31, which will then permit the stopperto be easily lifted from the bowl.

A fork-supporting and operating pin 32 is transversely mounted in hearings formed in the walls of the offset portion of the chamber 18, said-pin preferably being formed with a squared enlargement 33 which is adapted to engage a corresl'iondingly squared opening 34 formed in the inner end of the lifting fork 29. A gland, formed by, packing 35 and nut 36, as shown in Fig. 2, is provided to prevent leakage past the pin, 32.

An operating yoke 37 is rotatably secured to one wall of the chamber 18 by the threaded pin 38 while its opposite arm is formed with an opening 39, having an open slot 39 to permit the entrance into the opening of the flattened end 40 of the pin 32 which is held by means of the set screw 41.. It will be seen that the slot 39 is slightly less in width than the diameter of the opening 39, so as to form a pocket 39 for receivii'ig' the circular portion of the flattened end of the pin, and thus prevent its escape therefrom when held by the set screw ll. The yoke 37 between its ends is provided with lugs l2 having apertures 43 which are adapted to be loosely engaged by an opcratmg member i l by means of the removable pin 45.

The operating member l i has a flattened section 46 and is engaged by a slidable member 4-7 which is adjustably secured thereto by the set screw 48. The upper end of the member 47 is formed with a screw threaded portion 4-8 to which is adjustably secured the lower end of the lifting rod 4-9, which.

rod may extend upwardly and have secured to 1t in any suitable manner, a hand knob or other operating part (not shown) By this novel construction, not only are tion and operation without departing, from the spirit of the invention and the scope of what is claimed;
